Scenario : You have made the decision to migrate all your operations onto WebLogic
Server. An application has been chosen from each department for the initial phase of
migration one from each of Sales, Marketing, Accounts, and Customer Service. The
applications will be deployed as individual EAR files to a cluster of WebLogic Server 9.x
instances, each with a pool of connections to an Oracle 10g database that provides
corporate and departmental data services. The database team hopes to upgrade the
database to use Oracle RAC (Real Application Clusters) shortly, which will require you to
configure multiple sets of connections. Connectivity to the existing Service Engineer
Dispatch system is via a JMS message bridge. When a service engineer calls in with a
report, a message is sent via JMS to the Customer Service application deployed in
WebLogic Server. The customer record in the Customer Service database must be
updated with details from the message. It is important that the message is not lost
because the call management system is not able to resend messages. To address this,
the Customer Service application is accessing a persistent JMS Queue using an XA
compatible connection factory.
In the future, each department will have its own schema within the Oracle database and the
developers are writing their code with this in mind. However, for now, it has been decided
to store all data in a single, company-wide schema. Which of the following approaches will
make a future move to multiple schema simple, while making the most efficient use of
resources today?
A. Deploy an application-scoped Data Source module with each application.
B. Deploy a Data Source system module and assign it multiple JNDI names.
C. Deploy each department's application to its own WebLogic server.
D. Deploy a Data Source system module for each department's application.

Before deploying it into the test environment, you review the configuration of the Sales
department's Enterprise Application, which is meant to contain a JDBC Application Module
?you are concerned that it may not have been built correctly. Most of an application's
deployment descriptors only reference the JDBC module using a JNDI name. Which file
listed below is the only one that refers directly to the JDBC Application Module file?
A. config.xml
B. application.xml
C. weblogic-ejb-jar.xml

When starting WebLogic Server, the Marketing database is unavailable. Which of these
Data Source configuration options will ensure that the Marketing application can access its
database once it becomes available again?

The database team informs you that they have now implemented Oracle Real Application
Clusters (RA for the Customer Service database, and applications should connect to a
second database node if the primary node is unavailable. You set up a Multi Data Source
in Failover mode, which is configured to use two Data Sources PrimaryDS and
SecondaryDS, each connecting to one Oracle RAC node. WebLogic Server will fail over to
SecondaryDS if a connection test to PrimaryDS fails. Under what other condition will this
happen by default (that is, with no additional options checke)?

A. If a connection to PrimaryDS is not released within Statement Timeout seconds.
B. If all the connections to PrimaryDS are in use.
C. If the administrator has suspended the PrimaryDS Data Source.
